Today is 2 weeks short of my first 6 months of Hellcat ownership, so I booked my Hellcat in for its first 6,000 mile / 6 month service.
I bought the car new (12 miles on it) from Unity Automotive in Leicester unity automotive leicester uk - Google Search
and the car is covered by a 3 year warranty via the "semi-official" UK / European importer, and Unity will service the car to maintain the warranty.
It's not cheap owning a Dodge in the UK for sure! £385 for an Oil & Filter service - over $450 USD at today's exchange rate. Over half of that cost is the price of the oil, which has to be the Penzoil Ultra and can't be anything else. It isnt sold in the UK officially, so has to be imported. I bought a small 1 Litre bottle a few months ago for top upsand that cost me around $50, so I think they have been very reasonable.
Back again in either 6 months or 6,000 miles again!
