I have a 115.117 which is slowly being brought back to daily driver status. Like you I have owned several 123's but this is my first 115. Here are some things I have noticed:
- Not many examples at the pick n pull yards.
- People who know the 115 are scarce compared to 123 knowledge base, but this sub forum has been really rich with 115 info.
- Parts in general are more expensive than the 123 and on at least one instance so far been hard to source.
- As mentioned, the car rides great!
I love the car and hope it will serve me for a few years as a daily until I get the bug for something else. I hope you get a 115, the more of us there are the better. Plus they just look great!
