- Buyer beware... / #BMW-F10 / #BMW-520d / #BMW-520d-F10 / #BMW / #BMW-5-Series / #BMW-5-Series-F10
I wasn’t very surprised to see that early, high mileage F10s are now down to around £6500 – inevitable I guess. But I would urge caution if you’re thinking of taking the plunge and buying such a car. The F10 is, of course, a decently built motor and it’s one of our favourites because there is little a 520d won’t do very well. But these cheaper examples will have done well over 150,000 miles and it’s at this age, mileage and price point where you can quite easily end up with a £7500 millstone, and cars don’t get more reliable with age. Start with the engine – the N47 is well known for timing chain issues and ignore anyone who says BMW sorted that out by 2010, because it certainly hadn’t. One 2011 car I saw with 180,000 miles (a 520d manual) had been fitted with a brand-new engine just 30k before so that might be a good deal. But then you have 180,000 mile-old injectors, turbo, high pressure pump, dual mass flywheel, manual box, electric steering rack, diff oil seals (a far more involved job due to the driveshafts with two integral CV joints) and so on. #BMW-523i-F10 and #BMW-528i-F10 cars with the N53 can have very persistent and pricey misfire problems – coil packs, injectors, NoX sensors…
It’s hard to say exactly when cars went from being rugged and fixable to being dynamically amazing but a potential nightmare to repair, but it was long before the F10 was launched. Truth is, cars like this as well as equivalent Vauxhalls, Mercs, Audis and so on are fine for the warranty period, but be prepared for a four-figure financial kicking if something goes wrong. I personally wouldn’t consider a leggy F10 or F30 unless it was stupidly cheap, but when even recorded write-offs are fetching frankly ridiculous prices, that’s unlikely. As ever, we’d take the £7500 you’d spend on a mega mileage time bomb and use it as a down payment on a warrantied Approved Used Car from a main dealer – or even on a deal on a brand-new one.
