...Was He Right? 18 years old and Mustang cost 225 at least as most allowed in state, may have to go elsewhere for insurance as well as parents buy as you do not have credit or enough is impossible. The Jag, which is mostly a Ford taurus is not financeable , just cash as 6 years or newer is limit, will be normal for 18 about 3-400 down and about 125 a month for insurance ful coverage which you have to have unless cash.Jag is worth if clean carfax and normal wear and tear and 130,000 miles or less is worth about 3000.00. New GT is 30,000 with tax, tag and fees which with 0 down will be with 10% APR for 5 years 660 a month+225.00 insurance is 885.00 a month and down payment of 1000.00, take 20.00 off monthly so 10,000 down will be 560 4 -5 years as Jag will be a lot in repairs as Old Taurus with 3.0 V6 and has to be paid cash so will not cost ave. of 100/month + insurance of 125 and enjoy as most do not know its a ford.
