There were two generations of Tigra, but both were based on Corsa mechanicals so will be no more or less reliable or expensive to repair mechanically than a Corsa.
The original 1994-2001 Tigra coupé was based on the 1993 Corsa B. It wasn't a bad car, but it wasn't particularly good either, just average at everything except how it looked. But the youngest are now 16 years old, which given that most cars are designed to last 10 to 12 years means most will be in poor mechanical and/or structural condition. Insurance is in group 21 for a 1.4, or 25 for a 1.6, which means it will be expensive (most new drivers go for cars in groups 1 to 4, maybe up to group 7 at a push). Insurers also tend to charge more for cars over 10 years old, due to the lack of available repair parts.
The second-generation 2004-2009 Tigra TwinTop, with folding metal roof, was based on the 2001 Corsa C. The youngest examples will still be within their design life, although older examples may well be worth avoiding. It only seats two, so may not be that suited to you if you have an active social life with a larger group of friends - you won't be able to take your turn at being the driver for nights out / days out / road trips. Insurance ranges from Group 15 for a diesel in "Air" trim level, to Group 26 for a 1.8 petrol in "Sport Rouge" or "Exclusiv" trim levels, so again will be more expensive than most new drivers will pay, but a later 1.3 diesel or 1.4 petrol in base or "Air" trim will be more affordable to insure than the first generation Tigra. Don't think of this model as a sports car - it is heavy, so will be slower than a Corsa with the same engine.
The Vauxhall is no better or worse than any other make or model.
The only way to know what it would cost to insure a vehicle is to ask some insurance companies. Nobody here has the foggiest idea of what insurance might cost you.
Yes, the insurance is bad. Very bad. Because 17 year old, that's why.
When you're 17, there is no such thing as affordable insurance. Well, not unless people call your mom "your majesty" or you just won a huge lottery, anyway.

the insurance cost will be higher than the cost of car
The Tigra wasn't a good car when it was brand new, Now it's an old car. Go figure.
Insurance will always be a nightmare for a 17 year old.
It is group 28 to 25 depending on model.
You need to be looking at cars in groups 1 to 5.
The higher the group the higher the cost.
Get quotes and see.
