Oh for sure, it's all banter, it's what makes forums like this interesting! Everybody does things to suit them, that's what car purchases and modifying is all about
Re insurance and remaps... I'm insure with Greenlight who cover everything like-for-like and are fully clued up when it comes to remaps and most other mods, I've been very impressed so far. Greenlight actually post on this forum too so are fully aware of what's what when it comes to modifications
Servicing costs for the LCR are around £100 for the annual and double or more or the major services. For instance, my 40k service (the first really big one) is costing me £230, it would be less if I wasn't fussy about using the best, long life oil. The next service is a fluid and filter change, so less than half that cost luckily.
Out of interest, who are you insured with?
