Son is trying to make a living at it. He's not good at a 9-5 job with ADHD, doesn't like being down to a timetable. Drives me crazy as he is incredibly messy and in encroaches into 'my' garage/bike storage.
He's doing a part time job at a small garage, but it looks like they are struggling a bit for work, and he helps out a friend with their car wrapping business (unpaid I think). The Aygo should make a good £1k profit, and the Leon probably £3k.
The Leon is a nice car, and he got if for £1.5k (64 plate) and should sell for £4k-5k. He's quite a bit of experience with these VAG petrol engines and it's actually far cheaper to buy a low mileage engine off a scrapped car. It's then relatively straight forward (not for me) to swap the 'dumb' part of the engine. All get's complicated with the ancillaries as many are coded to the ECU, so as long as the mechanical bit can be changed it's all good. Having done a few, he's aware of what get's damaged when engines are removed, so some plastic connectors for various components are snapped on a donor engine as they just cut everything off at the scrap yard. So long as you are careful removing the original engine, you've got all the necessary parts.
