Need inputs on buying used F10

[tejastarun]

Hello all,

I recently had someone rear end me in my beautiful E60. The other guy had GEICO and we all know how shit they are. They want to total my car because the price to fix it is 7k and my car value according to them is 6k.
I am fighting at the moment with all the receipts from FCP euro and BMW. Basically the car is mechanically all new. Including oil pan gasket, engine mounts, transmission mounts, diff mounts, all new control arms front and back, new sachs shocks and struts, all new hardware in suspension ( MEYLE and LEMFORD only), brakes including fluid, hoses are new ( Zimmerman and Akebono, fluid is Castrol racing brake fluid ). and many more under the bonnet parts. Transmission was also serviced twice by me. new fluid, solenoids and all gaskets and pans.... and the list goes on.. I also have switchback led angel eyes by removing the lens, quad bixenon setup and led all over the car. So it is definitely worth a lot more than what GEICO is saying.

In the event that I do have to buy a new used car, I was lookin at f10 with N55 or the N63 engine. I cannot afford to get a loan on the newer 2016 or 2015 cars since they are way above my budget.
I have read in some of the threads that N55 is a damn good engine and much better reliability compared to the N54. On the other hand N63 is tempting... I did want a v8TT for a long time. But I read in lot of posts that 2014 and below are shit.
BMW did give a CCP but I am not sure on how good it is after the CCP.

I am not shy to DIY. All the work done on my previous is DIY in the parking lot. But I am not willing to spend a lot on parts and work every weekend.
I found two really good deals, one for 2013 535xi and the other one is 2014 550xi. Both have close to 100k.

I am yet to test drive them. Could you all please tell me your experiences with these two engines. I do not want to go with the N20 because of reliability issues and not enough power.

Please advise.
TIA

Your maintenance and upgrades are worth nothing to an insurance company. One NEVER recoups the value of installed upgraded parts. You might do better financially parting-out the car. That said...

Personally, I would look to a 2014 N55. The LCI has some nicer features. When I bought my 1st BMW in 2015 I was looking at the V8. After some extensive research on the V8 I chose the N55 and I couldn't be happier.
