Some do look pretty hideous, but that just depends on the budget. If you ask me, it would be too hard to own a real Porsche Speedster or a Shelby Cobra because I'd be afraid to drive them. They are too valuable. My dad used to own a Speedster replica and his friend has a Cobra replica.

Replica Cobras can bring over $100k. "Factory Five" and "SuperPerformance" cobras are sought after replicas. This particular Cobra was bought at Barrett-Jackson for $55k in 2013. It is based on a C3 Corvette chassis. The Speedster was built by "Vintage Speedster", but "Beck" and "Intermecchanica" make replica Speedsters and Spyders that can sell for nearly $100k brand new. On ebay, my dad bought this Speedster for $20k. It featured a real Porsche 356 engine, but the chassis was from a 63' bug. That car was sooooooo fun. Everyone in town loved it. Our license plate was "2 Faux" so people knew it was a fake...
