Hi guys, looking for a good quality cup holder for my C3, found a few that looked cheap, anyone know we’re I can get a quality cup holder

Hi, There are various ones out there. Do you want it to fit over the E Brake handle? Do you usually carry a passenger? There are a couple that are removable. One style has a tab that will slide down between the seat and center console, and has a two cup and change holder. Another style inserts under the lip of the console and rests on the floor. Some are single use or double. Many of the Corvette Parts vendor catalogs carry them. 

I always thought the ones that slipped on to the parking brake handle seemed the most user friendly. The downside and the reason I never got them was because I use the parking brake due to being a daily driver in salted road country. I found that if you don't, the cable gets frozen up inside the housing and while you can still apply the parking brake, the spring is not strong enough to break it loose to release it.

E Brake ones are always in the way. Tough to shift, and prone to spills. I like to oil my cables for that reason. The center spring is a tad weak, but the ones in the drums are fairly rugged. Try hooking one back up after working on the trailing arms. 

I like the cup holders that sit in the passenger seat - in my case called "my wife"!😄
