Had a recurring engine light issue; Tyler and his team went at it 3 times and wouldn't rest until it was 100% solved. Most shops would keep on changing (expensive) parts to fix it, however to their credit the USP guys looked at the hard to find items (small crack in the plastic tube), missing seal on the vacuum pipe (likely from date of mfr in 2008!)!! Then they test drove it for a number of miles over two days to make sure it was gone...so that's why I will be a continuing good customer at USP Euro Car
