Hi, I am driving Volvo 850 SE 2.5
recently suspect the rear bumper loose already
need minor repair and maintain

normally I repair and maintain near safari pandan perdana
any 1 know which repair shop is creditable with reasonable price?

FC is bad, 95% city
Full tank 58L normally can last 400km only
(14.5L/100km or 6.9KM/L)
any recommendation to improve FC?
