If he was looking at SL's then i really do not understand the Cayman as a suggestion? Its dynamically pretty much the complete opposite to an SL with a completely different feature set. Someone who wants an SL wont want a Cayman, and vica verca.
The only thing he knows about cars is what his mates in the pub spout out.
One of his mates suggested an SL350, the other an Audi A5 Coupe.
He's now asking me as he's quickly realised he's pub mates are talking out of their poopers.
I simply asked him - what do you want in the car? He instantly started talking about a race car feel for when he's on his own and wants some fun, but with some refinement and class etc so he could take the Mrs out on a weekend to a posh pub, park it up and admire it from the pub garden.
