cantdrv55,
I like your handle (cantdrv55) - You're not alone there!
Anyhow, another factor you can add, to improve the odds for positive results, is to buy him a copy of software for his computer.
Specifically a drivers-ed program. There are several companies that make PC software that simulate street driving on the computer. I'm not talking about Need-For-Speed, or Sports Car GT
- those are fun, but the drivers ed software is serious training to prepare students for driving on the road. The programs also provide grading and evaluation aspects to them - so parents can monitor the students progress.
I have considered the very same thing with both of my sons with my 914. Unfortunately they would rather play PC games (at age 12 & 14) then learn about cars. My two younger daughters enjoy helping a lot though.
So I've just decided to wait until their ready. I'll find a nice 914 /1.7 or I believe a 924 would be a good choice for them as well - in some ways better than a 914 in terms of drivability, A/C, etc. Either would not have an abundance of HP, but allows for some fun & pride of ownership. I would also support their involvement in the PCA where the tools are available to become a better driver - off the street.
But I don't want to corner them with Porsches. I suspect I'll have to learn about Hondas, Nissan's or Toy's, but if that's what it takes to support them in their choices - so be it.
Keep pondering.
