Have between 10-13k to spend. Really deciding between a Lexus GS 300 or a Volvo s60 R or possibly an acura in that range? Anything others i should be considering? Looking for an entry level luxury seden that gets above average gas mileage...was thinking about a 99/01 cobra, but to be honest if I get an 8 cyl its going to be an 03/04 cobra, which i need an extra five for..
