Hi nikola_bb ,
1) I don´t think the gen4 interior is smaller, but I´m not 100% sure.
2) I had my 2014 CR-V Diesel for almost 9 years and 232.000 km - no rust issues. I live in an area where salt is used in the winter sometimes (Black Forest) However, my car has always been parked in a garage.
3) That should be possible (aftermarket installation), but it may not be easy - because CR-Vs are rare in Germany.
4) I had no issues whatsoever with my gen 4 CR-V. That car turned me into a Honda fanboy, whereas before I have not been loyal to any brand.
5) Definitely not, Halogen was standard. And the Halogen is really not the best.
6) As mentioned before - I sold my CR-V on January 7 with 232.000 km. The car was in very good technical condition, the engine running smoothly ( I used 0W30 Petronas Syntium oil). The engine should be good for 400.000 km at least. I rarely exceeded 120 km/h on the highway, I must add. For necessary service at 120.000 km, please use Google.
7) I had the pedal box, and it was a very useful modification. The throttle response was so much better. I can offer the pedal box for the 120 hp engine to you for 110 Euros including shipping.
Regards,
