Isn’t that $99 a month lease like those $19.99 mufflers Midas used to advertise back in the 1980’s, i.e. If you make it out of there for $99 a month, somebody at the dealership is going to be unemployed tomorrow morning? Plus the fact that you will only be allowed to drive it to church on Sunday, if and only if the church is less than 10 miles from your house (round trip). And you must be a retired Navy Admiral with super-duper extra extraordinarily exceptionally qualified credit others may not qualify for this offer restrictions apply.

Leasing a car has many drawbacks, in my opinion
They only allow limited miles, far less than the average US driver actually drives
Not to mention, since the car isn’t yours, you must buy expensive comprehensive insurance
