Need some advice on best years, transmission, V8 vs V10, spider vs. coupe.

Any help would be appreciated. Presently we own several Porsches and Aston Martins but feel the urge for a good used R8 in the fleet.

Thanks in advance for the collective wisdom here.

 

Best v10 manual trans any year. Common issues are minor (ac compressor and leaky magnetic ride suspension).
