Have a Thunder myself (L98 M6) and there hasn't been any cause for concern, but its more just a weekender. probably spent 6-9 months back in 2018/9 looking for what I wanted.
Kept tabs on the prices of them over a few years, back in 18/19 they were in the 15-25k range. Went up to 25-35k around 21/22/23 and seem to have gone back to 20-30k for similar stuff recently. Obviously there are anomalies in that, but thats roughly the guide ive kept tabs on.
