It's important to get the service records for the car to ensure all maintenance has been performed as well as any issues that the car may have had; the 13' F10 M5 was the first year for this car in the US and there were several documented issues (my first F10 M5 was a 13' and it spent a bit of time at the dealer before upgrading to a 15').

I noticed both listings in your post were 13's; IMO if you could afford a little more I would search for 14' or newer LCI.

Make sure you buy a warranty to ensure no large cash layouts down the road as these cars are not cheap to fix when something serious goes wrong. At this point 13's and most 14's are out of warranty so you would need to see if any vehicles you're buying have a warranty that may be transferable.

Do a search and you should be able to find quite a bit of information as this topic has been discussed quite a bit.

Good luck.
