Martin,
Welcome to the forum! :seeya: I'm the former owner of Chris’s (Gherkin) green supercharged beast (a beautiful car, BTW) and the current owner (second time around) of an LS6-powered Stalker (jokingly called Storkers :jester:) that I built, sold and bought back. Up front, ‘ALL’ of these cars—regardless or make, regardless of who built it, no matter how well sorted and maintained, no matter what drivetrain—will require a bit more attention when it comes to maintenance and, of course, breakage. Yes, sadly, they do break. Having said that, I can’t name a single car I’ve owned that’s more fun than a well sorted, dialed in Seven, especially when you are driving the car the way it was meant to be driven. From crossflows to V8s, these cars are challenging to own, yet very rewarding to drive. Any of them will frustrate you, yet keep your fun meter pegged in the red. You simply have to be willing to turn a wrench every now and then; comes with the territory.
As for TMW’s, a few of us here (including me) have had issues that we, for the sake of the Seven community, are careful about sharing. From what little I know, let me stress that the quality of the Birkin (as delivered from the factory) has ‘NEVER’ been the issue. The details of my personal experience with TMW’s, I keep under my hat, but will share one-on-one (privately) if interested. Having said that, do not let my words (neither now nor later) sway you from purchasing a Birkin; they are very well designed, excellent examples of Sevens. A well-sorted, dialed in example is the Birkin of Folis Jones who has been tracking the car for a few years (see photo below and link to his videos).
I don’t know where you’re located, but JeffersonRaley (JR) and I will be running at Texas World Speedway Feb 28-March 1. JR will have his Birkin at the track and I will be bringing the Storker. It may be an opportunity for questions, etc. if you could make it to College Station, TX that weekend. Good luck with your Seven search.
Shane :cheers:
