There's a guy just along the road a bit, who's vehicle-related behaviour makes me both smile, and cringe, for the poor vehicles. He seems to be a painter/decorator, with absolutely no mechanical sympathy at all.
He used to have a Transit van, one of the early sloping front ones, with one of the noisiest engines ever. These are prone to being difficult to start as they age, but his, despite his best (worst) efforts stared better than one might expect. With those, and many older diesels, it is important to wait for the glowplug light to extinguish, then start it immediately. His technique, with all vehicles, is to jump in, turn the key fully, and churn until it fires, then rev it mercilessly until it will pull away. Of course, there are clouds of grey smoke from the partly atomised and unburnt fuel. The Transit coped with this, but eventually died for other reasons.
Transit was replaced with a Citroen Dispatch, of 2010 vintage, I think. Despite being newer, and generally more tolerant of early starting, this one objects, taking significantly longer to start, and struggling to run properly for some time. It seems to work for about 3-4 weeks at a time, before disappearing for 'repair' and returning a week or so later for more abuse.
Recently, there was some black scuffing over and behind the nearside front wheelarch, which appeared to be from a truck wheel. I'd expect it to be his fault, not the truck.
Van broke again 10 days ago, but has returned today, with the scuffing polished out, but the dents remain, and the rest of the van still dirty. It sounds awful, poor thing, but is again pressed into service, as he appears to have broken his pride & joy Mercedes coupe. It makes me laugh when he has to use that for work, as normally he will not put his young daughter in it, preferring always to use the child seat in the van.
His wife has a Fiat Bravo diesel. That gets similar abuse from her as the van does from him, and sounds worse every time I hear it. He never drives the Fiat, and she never the Mercedes.
