I think these are the only two cars in NFS:MW that can do sub 1:35's at Rockridge and Union without using speedbreaker. Most of the other cars can barely do sub 1:40's.
Most of the other cars don't corner well enough. The BMW M3 corners well, but in stock form it's low on power. It can be hacked to have 6 of 7 peformance uniques (all but the supercharger), which makes it about the same as the Lotus Elise.
