Depends on what you get, buddy.
My 535 kicks ass. Perfectly great engine and superb highway performance. A manual would be nice for around town performance, I guess. The only problem is not driving too fast - 90 feels like 50. But, that's why I've got a Valentine One
M20 powered 525....eh, I dunno. Maybe with an EAT, but I've never driven one, so what do I know? The M50 525 that I looked at last summer was alright, though.
