I wouldn't spend $$ on a Spanish-built SR Mauser. The Spanish-built Mauser don't have a very good reputation for quality of manufacture or materials. If you're going to spend $$ on a SR pre-1898 style Mauser, Swedish-built 1894/1896/1938 styles Mausers are the best place to put your $$, at least IMO.

It is your $$ to spend, but having rebarreled a couple dozen SR pre-1898 style Mausers, I wouldn't put my $$ into any action that was a Swed or, maybe, a Ludwig Lowe-built 1895 Chilean.
