Maybe you consider this cheating but you could have saved your game after receiving your ticket, making a back up save, open the ticket & if disappointed you could reload your back up save & open your ticket. Repeat this until you get a car that you're not disappointed with.
i got a really good car which i already had. The Nissan R92CP Race Car '92 i was pissed because i purchased it for just under 4 million the week before.
