NB Check Longitudinal Carriers before Purchase

Moin together, we are looking for a MX5 NBFL and I have already read myself well and know mostly what comes to me. I try to get a sportive, mainly because of the 6th gear for the daily highway, but the market is so thin, I have to take what fits. In the area of Hamburg there are not too many and I still shy away from picking up one from further away and trusting the dealer or driving for free. The sleepers have to be taken into account with every NB, but with the longitudinal support it will be difficult to repair. Do you only look at mobile?
