We bought a used car at a distance from their Jaguar Watford dealership but I would advise against this unless, like us, it's the only place that has the precise model you want. They are unreliable, disorganised, uninterested and uncommunicative. If you do go ahead take voice recordings of your conversations and get what is agreed in writing.
Initially, I paid a refundable fee to reserve the car on-line, where it said it would be held for 5 days but, on speaking to them, they insisted it was only 24 hours. So, next day, I tried to progress the purchase by phone but nobody would speak to me or phone me back because the rep I had spoken to before was on a day off. The rep was back next day but all he was interested in was selling their bundle of overpriced insurance extras (wheels, tyres, SMART repair etc). It was like pulling teeth to discuss the car itself or get clear details of finance options and their T's&C's.
We nearly walked away, and only decided to proceed because it was Jaguar approved used, so had the manufacturer's inspection and warranty as a back up.
We therefore paid a deposit to secure the car but, despite this, it remained for sale on their website for days afterwards - and they even increased the price. They then tried to charge me that increased price when I came to settle and required me to send them evidence of their own lower price in order to drop it back down!
When we went to collect the car I found a hole in the upholstery of one of the seats, which had not been declared. Their initial response was it was a used car so should be expected (it was 2 years old) but, after a bit of a discussion, they agreed to pay for me to get it repaired "As a gesture of goodwill".
Furthermore, they tried to hand the car over without a set of floor mats, which had been agreed as part of the purchase. They tried to deny this agreement but, luckily, I had an email to prove the opposite, so they said they would post a set on to me. The puncture repair and reinflation kit were also missing, but they were able to find a set before we took the car away.
Bizarrely, after the decidedly unpleasant experience of the purchase, their service improved markedly once we had taken delivery. The missing floor mats arrived within a few days and I was fully reimbursed for the upholstery repair (even though I messed up by initially sending the wrong account number for payment). I would give the after purchase aspect of their service 4 stars but it wouldn't make me go back and buy another car from them.
We have had the car for nearly 2 months now and it has been absolutely fine. It would just have been nice to enjoy the experience of purchasing it.
