The MK4 R32 is very iconic but not actually very good I believe. It's a heavy lump of a car and isn't that fast but, I think they look great and I'm sure it will continue to hold its money.

E46 Emm-Free is always a good but slightly predicable choice. I've had an E36 but never my own E46. Everyone I have ever spoken to who has had/driven one loved it.

Ever considered a Renault? I've got a lot of love for the Clio and Megane Sports, especially in liquid yellow...
