We don't have a California. We thought hard and looked a lot. The California spec is good but it is fixed - like it or lump it. Eventually, after hiring one, we decided the California spec did not tick our boxes. We wanted extra space, so a LWB, hot water, a built in toilet, not keen on pop tops so a high top fully insulated. None of this is available in a California. So we went cautiously down the conversion route. One needs to be careful, there are excellent converters and rubbish ones. So we purchased a top spec T6 LWB 150 DSG and had it converted by a VW approved converter with full VW warranty on the vehicle and 3 year warranty on the conversion. Cost was about 15k less than a discounted California. However, this was less important that getting a van that ticked our boxes. We love what we have, not everyone will. On resale value, we have been offered, twice, more than we paid for it. Yes a small sample compared to resale Californias. We have had a couple of warranty issues re the conversion. But pleased to say the converter fixed the problems within 72 hours of contacting them and paid for my travel plus hotel to return the van for the fix. We are delighted, but we don't have a California and did not want one. There is no right or wrong, purchase what will suit your lifestyle.
