I have never driven one but i did sit in one which is one of the downfalls with the elise. Im sure it is the same with most sports cars but it really is an art form just sitting in the thing. Having said that once you are in it, i thought it was very snug and comfy but like i said it havent driven one. The best thing to do would be to go down to your local dealer and test drive one. With reguards to the engine, i know it is only 4 cylinder, but it is extremely powerful, especially with the car being so light. Hope you dont mind me asking, but what car are you driving at the moment?
Hope this helps
