I genuinely expected to see a lot of replies all stating that spending £8,000 on a car you have for 3 year is anything between silly and insane. I’ve not been in the GLA but all reviews I’ve seen for that class of car haven’t included Mercedes as a class option, let alone leader. If it were me, I’d be looking to spend less and have some money ready for my next car and not get a prestige badge. What you should be looking at, I’m afraid, I can’t help as I’ve not kept track of non BEVs for a while.
Given the GLA costs approximately £50000, Im looking at the level of equipment provided on the car, so I can compare if it is available for less on other cars. My circumstances dictate that I would rather pay the 8k advanced payment and not £8300 vat for the government to waste were I to buy the car myself.
