What's different about buying in Connecticut

Connecticut charges 6.35% — but 7.75% on vehicles over $50,000, a luxury threshold that catches a lot of modern trucks and SUVs. Doc fees are uncapped and all over the map: we've seen the same brand vary by $500 between stores twenty minutes apart.

Trade-in mathYour trade-in's value is deducted from the purchase price before tax is calculated. A $15,000 trade saves you $952 in tax here — which usually makes trading in beat a private sale once you factor in the hassle.
