I've been following BaT since day one, but have yet to buy a car on the site. I have bid, seriously on 3-4 cars. I have also had some serious conversation about helping to launch a similar site, as BaT started to get very busy about 18 months ago. These were pitches made to me.
There are a lot of great, fun cars that do not make it to BaT these days. All about their shelf space. They won't list them. OP mentioned a TT. I have friend who almost gave away a 2003 225hp coupe, which mechanically was perfect and had been well modified. BaT would not list it. Can't recall why. Odometer?
BaT, with it's simple platform and reach, coupled with their very reasonable fees for really high end cars, is just crushing the more established car auction houses. At one point it surprised me that they had not yet sold out one. Not now. They were acquired by Hearst Autos, the group that owns Road and track as well as Car and Driver, in June. Sounds like they are going to fuel it as needed. They have created quite a machine. They had no need to sell, other than to keep growing. Founders are still on board. I bet they had plenty of suitors.
For a car seller, BaT delivers great results if you have a car that is popular, and of interest. If that car comes with low mileage, and is "fully booked" from a service standpoint, that's best. Also, either no accidents, or if a minor dent and respray has taken place, all of the exact repair details. Even better if it's the "right color" for the car. The best selling colors. Think graphite over red leather for a S2000. Limited modifications, or none.
If the car has some real “provenance”, in terms of prior owners, even better.
Frankly, what sells best and highest are absolutely mint, perfect examples. We have seen that over the past few months. The M3, the 240Z, last week’s Porsche 993.
Sellers should have the best professional pictures possible taken to present the car. Well worth the money. They deliver. If you do all that and work carefully with them to "write" the auction, as a seller, I would take my chances there over any other outlet.
The use of a reserve price is something that they can guide you on. I'm a chicken. I'd put a reserve on my car{s}.
Now as a buyer, more and more of the cars are as I described above. Pristine. Perfect. And it seems like a couple or there people come out of the woodwork who bid what to what look like irrational levels. I compare some of the sales prices to what cars sell for on various brand enthusiast forums, where the owners have often fanatically maintained the cars, and BaT seems to outpace them. If you want a driver, maybe a car to autocross, or track, and it can show some wear and patina.....and maybe an odometer that pushes 100K, rather than 15K, you may not find that car anymore on BaT. And you may save thousands on it elsewhere.
Now if you are a collector, and you really, truly know your stuff and have people around you who do, some of what is selling on BaT is absolute best in class, and in some cases destined for a museum. That's not a game for the faint of heart.
BaT is turning down a LOT of cars to be posted, despite the big volume of daily auctions that they run. Those cars are being sold, IMO, on the enthusiast sites, and even on Craigslist. It's amazing what a national search of CL can yield. My brother bought an S2000 for about a third of what a minty one sells for on BaT. One of his long time drivers is a 911SC that is "well worn", but drives like a dream. BaT would never touch it. You would be hard pressed to find a more fun one.
If I were selling a car that I thought would generate the interest, I would be all over BaT. If I were buying, I'd look for one where the circumstances are such that the particular car might not be that "hot". Often a car gets a bad rap early on, for no good reason. Maybe the auction is closing on a strange date, a holiday, the wrong time of the day. Maybe the pictures are not great, maybe......some cars sell at prices that look astoundingly high, and others, simply "too low."
I'll give you an example. If you want to buy a car to drive and have a blast with for say five years, you probably can deal with some surface rust on the frame....and maybe you even take care of it on the cheap. If you are a collector, no way. I see people ALL the time turning their noses up at "rust", when it's very minor. I have driven cars for 15 years, in New England, with much worse, and real rust.
If you play as a buyer, you need, IMO to know what you are doing, and how to value what you're looking at.
My son and I follow BaT.....like addicts. I had one car that got away, because of a couple of irrational bidders. I really wanted it. An Audi B6 S4 Avant, Novaro Blue, Manual, and....a rare "sunroof delete". The car needed to have the engine pulled, and $5K or more of work. The bidder was not going to be denied, particularly when he read comments about the color, the lack of the sunroof, etc. I bid $5K more than I thought was sane, and it sold for something like $20K over that. Have not seen a thing about it pop up on any of the Audi forums in the years since. The buyer ignored comments about what replacing the timing chain and guides, clutch and flywheel....and maybe more, would cost. This was no collector car.
I'd figure out what you really would like for a car, get up to speed and then look around and get educated about how, in what price range, and where they sell. The various car forums are a gold mine. I think we have a number of enthusiasts in our community.
For what you are looking for, you need not spend a ton, or go to BaT. You can check out the prices for a nice, well maintained older Cayman S, and then....check out a mid 2000’s Boxster S. The Boxster is a great driver. With a bit of work and the right tires...a real howl. A friend just bought one for about $10K.
Dollar for dollar, pretty hard to beat a Miata. Right,
@Philpug ?
Fun stuff!
