I know the simulator has not been out for even a month yet, so may this isn't the right time to ask this question since there are 1000+ cars....
But what car do you think is the ultimate sleeper in GT5? The car that is underrated and no one could have guessed how much potential it has?
Mine is Honda's 1966 S800 - This little turd corners like no other car I've seen in GT5 for its class.
For me, it was a '70 Dodge Challenger. Everyone would assume the car is fast in a straight line, but the cornering abilities exceeded even my expectations, and made the car a great all around car in the game.
Easily the Mazda Furai Concept '08 for me. It doesn't have a high BHP at around 548 BHP but with weight reductions it's only 675kg, has a high top speed and sticks to the road almost perfectly. As an added bonus it looks sick and mean from the front.
I've been trying to do the Japanese Classic race with the S800, I can gold the first 2 races, but the straight at Grand Valley is too long and I always get passed at the end. It takes the turns fast though.
I think the best fast inexpensive car is the Tommykaira ZZII '00. Not the small one that's a prize car. About 542 hp tuned (I said more earlier but I just checked). 1000 Kg. stock. Mid engine AWD that isn't tail heavy. Stock suspension is dialed in. Only used and hard to find but was my go-to horse early in the game. About 80K Cr. Did 202 MPH at Daytona without a draft.
I have 74 cars plus I driven most of the special section cars and the best handling is the Vauxhall Astra Super Turing Car '04. 624 Hp/1000Kg/front engine rear drive. It just doesn't have any faults. As predictable a car as you can get.
And then there is the Gillet Vertigo Race Car '04. 935 hp/ 780 Kg. I just check the stats. That is tuned. Sounds crazy and it is. Very hard to drive. Not recommended for the faint of heart. But if you want a challenge and you want a car capable of doing the Rome street track as fast as the 4 mil. Cr. Peugeot 908 HDI FAP for about 200K Cr. used, this is it. I don't mean to scare you off this car, it is possible to master. In truth it has certain capabilities that few cars have. Like after a sharp turn it takes most cars too long to get going again due to the driving aids. Not this car. It makes sharp turns fast and gets going like my Formula GT.
'49 VW Beetle.
I'm sure a fully tuned Prius would be quite a surprise. The question is, would anyone waste that much money on a Prius.
I found a '99 Honda Insight in the used car lot and if I end up with a big pile of credits at some point may tune it.
