    You beat me to this post.

    Seems like a solid design. The timing chain makes me scratch my head but hey, it's a chain and not a belt.

    I thought the chain was odd too, but it may have been done for room/ space reasons to shorten the overall length. But the 6 cylinder can still get serious ponies out of it and last and last.

    Still going to suffer from the problems of all modern BMWs. Cooling system problems, brittle plastic couplers, electronic gremlins, rod bearings, oil pump failures and so forth. Everyone I've known that has a modern BMW has serious problems once they start to get some miles on them. I tell you one thing Toyota mechanics are getting some serious cross training, Mazdas, Subarus and now BMW. I kind of wonder how Toyota's strategy of out sourcing so many of their cars is going to work out over time. We all know GM shot themselves in the foot after slapping new badges on platforms and selling medicore cars.

    I agree with you SilverMk2, Germany has a way to over complicate things and make even simple maintenance a nightmare. I hope the new cars are as good as our old MK2s . Time will tell.

    I'm looking at it from the "I'm never going to own or work on a new Supra or any BMW" point of view.

    Well if there anything like modern BMW parts there going to cost a arm and a leg. When I purchased a 318TI for my wife it needed a tune up so I said I might as well replace the spark plug wires. Looked and 4 dam wires were almost $350 and no cheaper on ebay. I know BMW parts are expensive and the 2020 Supra engine has less power than someone its older BMWs

    Ironically you'll probably be able to get parts from Toyota cheaper than BMW. I have a brz and parts are almost always cheaper from Toyota sometimes significantly.
