Cars in this category are $15000-$17100.  I picked the GM vehicles that best represent that range.  The Grand Am SE1 could work too.  There are a few Chevys that are in that price range or lower but they are smaller and not as nice.

I wasn't sure whether to put the Century Limited or the Regal LS.  But since the Regal can compete HP wise, it got the nod.  Also the cheap Impala could fit, but the 3.4 V6 engine isn't powerful enough.  These 6 cars are extremely close in price, power and size.

I didn't want to give too much space to the coupes.  For the lesser versions of the Camry and Accord, the Monte Carlo, Grand Am, lesser Grand Prixes and lesser Aleros could compete favorably. Also the Camaro Convertible and the Firebird's sportier car are like their GM counterparts listed

The Impala is a new add, but fits in well, especially for the price and Trip computer.  The Intrigue and other Oldsmobiles seem to be built in the model of the Japanese cars.
