Just a quick ask to see what people have retrofitted to their cars, mine is a 2015 and was very odd spec, it came with some very high end options then some were missing (like it has HUD).

I have done the below

Traffic sign and lane assist
Fuel burning heater with remote
Blind spot (still not fully working.. help!)
Radar cruise control
illuminated kick plates.
Front fogs
Full SVO Kit
LED Headlights
Genuine rear lights
Roof Rails and genuine RR roof bars
Android headunit
Climate screen
Android rear entertainment

Next is full massage seats (let me know if anyone has any)

I have fitted a dashcam! A heap of extra security, plus window security film behind the C pillar.

I ordered my car with 'everything' because I plan to keep it for many years. I am considering electric deployable side steps, but I cannot decide if I want them or not. They seem terribly expensive.

I am wondering if you are doing so many extensive upgrades it is not more viable to buy a higher specced car in the first place? Or is it the fun of tinkering and the satisfaction of having new toys over time vs all in one go? L405 P400e Autobiography (MY2020)... Silicon Silver / Espresso

I like to tinker and I find it more of a hobby. I could have brought a much higher spec but I want to build one the spec I want. I find you never get the full spec you want.
