Have to say, I agree with this 1000%.
Is an Elise-chassis car the most sensible thing ever? No. It'll squeak, it'll leak, it'll rattle, you'll never hear the stereo and it'll ice up on the inside. However, every single journey you do will be utterly memorable and it'll teach you more about driving and feedback than anything this side of a Caterham. The Elises are second only to probably TVRs in terms of friendliness in their car community, and everyone you see on the road will give you wave. My 911 was my favourite car, but I have more memories of my VXR220 in 18 months than I do of 4 years in the Porker.
Buy the right one and you could run it for a year then sell it on, and not lose a penny. Tbh you don't need the big bucks, a V6 Exige is a monster but on the roads that matter an S2 111R with the 'Yota 2ZZ lump is just as quick, and more importantly just as much fun. If you want pretty much zero depreciation then an S2 Elise or Exige with that engine will see you right.
