The Lotus is great, but an apt is better. I agree with you that a Lotus can be a good investment, but like that kayak commercial, it's a one (accident) and done type of car. I strongly suggest you focus on getting your own place as a priority. The Elise makes a great 2nd car, not so much an only car.
