1. Which is the more sportier IS the 250 or 300.

2. They both come in Manual right?

3. Do they only take premium?

4. Going to buy a 2nd hand what the max milage they should have?

If you are looking for sport/power then the 350 is the way to go but as far as I know you can only get a stick in the 250 model. Ive been looking to buy a 350 as well and I found this leasing company (http://www.theleaseoutlet.com) with some really low monthly payments on a Lexus Lease (http://www.theleaseoutlet.com/Auto/Lexus_Lease_Specials.aspx). Only problem is I dont know much about leasing and would appreciate any opinions/info from those more knowledgeable. I really appreciate it...........cheers
