Designing a car for an oil filter change - Mapmaker
Compare a W123 MB. I could change the oil and filter in that wearing a suit. Warm the oil, pop one wheel up on a kerb, undo the sump let it all drain out. Cartridge filter, sited on the very top of the engine so pop the lid off, pull out the cartridge drop in the new one. All finished in under 5 minutes including refilling.
