The short version

Based on about 200 recent Google reviews with usable text (out of 300, after removing a few staff-praise and duplicate entries), this off-site shuttle desk is rated very positively for deposit handling, absence of insurance pressure and car quality. Reported downsides are occasional shuttle delays, a fee for driving into Spain, and a few mechanical faults. Web evidence is thin, mostly undated and partly about other branches, so it only loosely supports the review picture.
