I'm jealous. Short story. Freshman year in college, became good friends with another student in my dorm who owned an older, somewhat used Lotus Europa. Took many drives in that car, and he allowed me some wheel time on occasion. Never forgot those experiences and the pure thrill and exhilaration of driving a true sports car.
Finished school and was able to afford a used MGB-GT. No Lotus, but fun and a mechanical challenge. The car was totaled while parked on the street. And real life got in the way.
From then on it was "practical" cars. Demands of starting and running a few small businesses and all the financial ups and downs just didn't allow for the time and expenditures for a Lotus.
Fast forward 30+ years. Finally purchased an Elise. A dream come true. Wish I had done it years ago.
If your and your family have the wherewithal and agreement without problem, do it.
A few caveats. Learn to drive a manual on another car as many have mentioned above. Immediately get some driver training with a qualified instructor who knows mid engine cars. HPDE at a track is probably a bit too much at first, an autocross program might be best. These cars can be a handful when driven hard and a controlled environment with proper instruction is needed.
Trust and ability are gained through experience. You are young, and have a full life ahead of you. Without self restraint, common sense, and a mature attitude driving a Lotus on public roads, you are doomed to be another anonymous highway statistic. Or at best, trash the car.
