My 2010 has 3200 miles on it all original and not a single leak of any kind anywhere. The biggest plague of the L99 is the afm lifters. They will probably be a little noisy for a second or two on cold start up but should clear up and quiet down pretty quickly. If they don’t clear up quickly I would pass or automatically plan on a cam swap and lifters. Odds are with that low of mileage you won’t have any issues from the for a good while if ever. The vvt is pretty reliable and a non issue largely.

Also seems L99’s are a little more sensitive to octane rating in the fuel. If it doesn’t run that great fill up from empty with fresh premium and do the fuse pull. Both of mine had regular in them when I bought them and those two things do make a decent difference as far as power goes.
