Lee, you'd be amazed how hard it is to get a demo at home, even on well regarded models.
But I have to agree with you.
I really really struggle w the UK Kuzma dealer, I wouldn't touch the two GPA Monaco UK dealers, I not going to pay above the odds (£20k) for a TW or SME etc.
I don't rate the £15k AMG.
That leaves Brinkmann and one of my other "left field" tts, the Primary Control Kinea DD
I suspect I might have to pay for the luxury of a home demo of the Kinea, but at least I'd get one.
Brinkmann's a somewhat odd company as they have the Bardo/Oasis with a really good low torque DD motor, but then the Spyder/Balance is belt drive.
